/ Ice Screw Sharpening

This is by far the best tutorial I've found on ice screw sharpening and exceeds the information supplied by black diamond and petzl by a long shot. I think I could probably follow these instructions without the need for a vice and without having a ground rounded file although those things would significantly speed up the process.

In reply to Nick Russell:
I use a similar technique I devised my self but it can be very time consuming for badly damaged screws, I can see how to cut some corners using these instructions and also where I was paying too much attention to detail where it wasn't needed before.
